Precision workstation upgrade
This 16 GB kit (2 x 8 GB) of DDR3L 1600 ECC registered RDIMM memory is built for Dell Precision R7610, T3600, T3610, T5600 and T5610 workstations. It targets IT professionals maintaining server-class infrastructure who need validated, registered modules with error correction. Standard desktop systems cannot use this memory.
Sustained workload stability
Registered buffering and ECC functionality maintain data integrity during continuous multi-threaded operations such as virtualisation, rendering or database tasks. The CL11 latency at 1600 MHz delivers consistent throughput without the errors that unbuffered memory can introduce under prolonged load. Mixing with unbuffered DIMMs is not supported.
Low-voltage thermal profile
Operating at 1.35 V, these modules reduce power draw and heat output compared to standard 1.5 V DDR3, easing cooling demands in dense chassis. The absence of a heat spreader keeps the profile low for tight DIMM spacing while JEDEC-compliant construction ensures reliable operation within the workstation's existing airflow design.

Questions about this item
How much power does the 1.35 V DDR3L kit draw compared to standard 1.5 V DDR3 when the workstation runs all day?
At 1.35 V the DDR3L modules consume less power and generate less heat than 1.5 V DDR3, reducing total system draw during continuous operation.
Which Dell Precision workstations must I already own for this 240-pin ECC RDIMM kit to work?
The kit is validated for Dell Precision R7610, T3600, T3610, T5600 and T5610; it will not fit standard desktops or unbuffered memory slots.
Can I add these CL11 1Rx4 registered modules alongside older unbuffered DDR3 DIMMs I already have installed?
No — registered ECC RDIMMs cannot be mixed with unbuffered memory; all slots must use registered ECC modules for the system to boot.
